ABSTRACT
Objective:To explore the application value of humidifying high-flow nasal cannula oxygen therapy (HHFNC) in children with pediatric intensive care unit (PICU) after weaning.Methods:From January 2018 to October 2021, 42 children with endotracheal intubation admitted to PICU of Tai′an city Central Hospital were prospectively selected and randomly divided into HHFNC group and nasal continuous positive airway pressure (NCPAP) group, with 21 patients in each group. The blood gas analysis [arterial partial pressure of oxygen (PaO 2), partial pressure of carbon dioxide in artery (PaCO 2), PaO 2/oxygen concentration (FiO 2)], blood oxygen saturation (SaO 2), comfort, non-invasive ventilation time, and total hospital stay of the two groups of children 1 hour after using HHFNC and NCPAP were compared, and the rate of reintubation of trachea within 48 hours, gastroesophageal reflux, nasal injury, facial skin indentation, abdominal distension, and pulmonary air leakage were recorded. Results:There was no significant difference between the two groups in terms of blood gas analysis (PaO 2, PaCO 2, PaO 2/FiO 2), SaO 2, pulmonary air leakage, non-invasive ventilation time, hospital stay, and reintubation rate within 48 h after weaning (all P>0.05). Compared with NCPAP group, HHFNC group had higher comfort, lower incidence of facial skin indentation, gastroesophageal reflux, nasal injury and abdominal distension, and the difference was statistically significant (all P<0.05). Conclusions:HHFNC and NCPAP can both be used as the transitional respiratory support mode after weaning, and the clinical treatment effect are similar. The HHFNC group has higher comfort, which is more conducive to improving the tolerance of children, reducing adverse reactions, and has higher safety.
ABSTRACT
Objective@#To analyze the epidemiological characteristics of acute paraquat(PQ)poisoning in children in southwest Shandong, and the risk factors for pulmonary interstitial fibrosis.@*Methods@#This retrospective study was performed on the clinical data of children with acute PQ poisoning admitted from January 2013 to December 2017 in 12 hospitals in southwest Shandong.All participants were divided into pulmonary interstitial fibrosis group and no pulmonary interstitial fibrosis group on the basis of the chest CT 14 days after poisoning.The epidemiological characteristics and risk factors of pulmonary interstitial fibrosis were analyzed.@*Results@#During the study period, a total of 307 children with acute PQ poisoning were admitted to 12 hospitals, of which 61 (19.87%) were suffering from acute PQ poisoning.Forty-nine cases with complete clinical data were analyzed, including 26 male and 23 female patients poisoned by oral.The age distribution ranged from 8 months to 14 years.Poisoning mainly occured from July to September of each year.The mortality of acute PQ poisoning was 8.2%(4/49), and the incidence of pulmonary interstitial fibrosis in survival patients was 44.4%(20/45). Statistical differences (P<0.05) were found between the pulmonary interstitial fibrosis and no pulmonary interstitial fibrosis, with regard to the times of blood purification, the time from poison exposure to blood purification, the application rate of glucocorticoids, the concentration of PQ in urine, the pediatric critical illness score, the time from poison exposure to gastric lavage, the white blood count at admission, serum creatinine, arterial blood lactate, PaO2, PaCO2, and PaO2/FiO2; however, there was no significant difference in the proportion of blood purification treatment, the mode of blood purification treatment, alanine aminotransferase, aspartate aminotransferase, urea nitrogen, creatine kinase and troponin.Stepwise logistic regression analysis showed that the time from exposure to poison to gastric lavage(OR=0.683, 95%CI 0.210-2.222)and to blood purification(OR=0.0133, 95%CI 0.004-0.042), the times of blood purification(OR=2.862, 95%CI 1.450-5.648), concentration of PQ in urine(OR=1.435, 95%CI 1.085-1.898), and the use of glucocorticoids(OR=0.190, 95%CI 0.048-0.757) were the risk factors for pulmonary interstitial fibrosis(P<0.05).@*Conclusion@#Early gastric lavage and blood purification, increasing the frequence of adminitrating purification appropriately, using low-dose glucocorticoids can reduce the incidence of pulmonary interstitial fibrosis of children with acute PQ poisoning.

ABSTRACT
Objective To evaluate the efficacy and safety of aripiprazole treatment for co-morbid attention defi?ciency hyperactivity disorder (ADHD) in children with Tourette syndrome (TS). Methods Forty four TS children with co-morbid ADHD were randomly divided into aripiprazole group and haloperidol group. The aripiprazole group and halo?peridol group received aripiprazole and haloperidol treatment for 12 weeks, respectively. Yale global tic severity scale (YGTSS) and Conners parent symptom questionnaire (PSQ) were used to assess the tic and ADHD symptoms before, 2, 4, 8 and 12 weeks after treatment. Side effects were recorded weekly. Results Repeated measure ANOVA indicated that the main effects of groups was not significant to the YGTSS scores (P>0.05), but significant to the PSQ scores (P0.05). The PSQ scores of aripiprazole group were significantly lower than that of haloperidol group. The adverse reactions of aripiprazole group were milder compared with the haloperidol group (P<0.05). Conclusions The present study demonstrates that aripipra?zole has the same efficacy in the treatment of tics as haloperidol, improves co-morbid ADHD symptoms, and its adverse reactions are much less compared with haloperidol.
ABSTRACT
To investigate the efficacy of high-dose methylprednisolone pulse therapy in the treatment of Enterovirus 71 [EV71] encephalitis. To determine whether high-dose methylprednisolone pulse therapy should be used, 80 cases of pediatric patients with EV71 encephalitis were randomly divided into steroid pulse therapy group and non-steroid pulse therapy group and their clinical information was compared using statistic analysis. There was no statistical difference in the duration of fever, duration of nervous system involvement, duration of hospital stay, blood pressure, and cure rates between the two groups [p>0.05]. The heart rate, respiratory rate, white blood cell counts and blood glucose of the steroid pulse therapy group were significantly higher than those of the non-steroid pulse therapy group [p<0.05]. Highdose steroid pulse therapy to treat EV71 encephalitis can't shorten the course or improve the prognosis of the disease. In contrast, it has side effects and might aggravate disease condition or interfere with disease diagnosis. Our study suggested that there is no beneficial effect to use high-dose steroid pulse therapy for the treatment of EV71 encephalitis

ABSTRACT
Objective To study the expression and signiifcance of phospholipid transfer protein (PLTP) and macrophage migration inhibitory factor (MIF) in mice with bronchopulmonary dysplasia (BPD). Methods Ninety-six 4-day-old mice were randomly divided into oxygen group and air group. Mice in oxygen group were exposed to a FiO2 of 65%, and mice in air group were exposed to air. On day 7, 14, 21 and 28, blood and lung tissue samples from 12 randomly selected mice in each group were obtained. The serum levels of MIF and PLTP were measured by ELISA assay. The morphological changes of lung tissue were ob-served with HE staining. Results The mice in oxygen group showed thickened lung parenchyma and obvious pulmonary ifbrosis. The radioactive alveolar count was signiifcantly lower in oxygen group than that in air group (P<0.01). PLTP level in air group was increased gradually from day 7 to day 21, and began to decrease on day 28. PLTP level in oxygen group was increased from day 7 to day 14, and decreased on day 21 and day 28. MIF level in air group did not change during the experiment. MIF level in oxygen group was signiifcantly increased from day 7 to day 21, and began to decrease on day 28. Conclusions MIF and PLTP may be good biomarkers for the diagnosis of BPD.
